EL1881CSZ

EL1881CSZ is a EL1881 low power sync separator. It is manufactured using Elantec’s high performance analogue CMOS process. This device extracts sync timing information from both standard and non-standard video input. It provides composite sync, vertical sync, burst/back porch timing, and odd/even field detection. A single external resistor sets all internal timing to adjust for various video standards. The composite sync output follows video in sync pulses and a vertical sync pulse is output on the rising edge of the first vertical serration following the vertical pre-equalizing string. For non-standard vertical inputs, a default vertical pulse is output when the vertical signal stays low for longer than the vertical sync default delay time. Application includes video amplifiers, PCMCIA applications, A/D drivers, line drivers, portable computers, high-speed communications, RGB applications, broadcast equipment, and active filtering.
